单选题 Early American industries depended largely on skilled artisans working in small shops to serve a local market. But the Industrial Revolution that started in England during the 18th century did not take long to cross the Atlantic. It brought many changes to American industry between 1776 and 1860. Because labor was scarce in the United States and wages were high, employers welcomed any new method that could reduce the requirement for labor.
One key development was the introduction of the factory system, which gathered many workers together in one workplace and produced goods for distribution over a wide area. The first factory in the United States is generally dated to 1793, when an Englishman named Samuel Slater came to America to build a cotton cloth factory. He built the machinery from memory, because it was a crime to carry factory plant out of England. The success of Slater's factory started a process of change that turned the northeastern region of the United States into an important manufacturing center. The making of textiles also meant increased demand for cotton, grown in the southern region for the United States. As a result, the nation became a major cotton producer.
Another important development was the "American system" of mass production, which originated in the firearms industry about 1800. The new system required precision engineering to create parts that were interchangeable. This, in return, allowed the final product to be assembled in stages, each worker specializing in a specific operation.
Just as Slater's new factory system was being introduced, an American named Eli Whitney made cotton production more efficient by inventing a machine—the cotton gin—that rapidly removed the seeds from the bolls of cotton. Removing the seeds by hand was a difficult task; Whitney's machine made the job almost easy.
Whitney also began manufacturing rifles in a new way. Guns had always been made by gun makers working in their homes or small shops. Because the guns were handmade individually, a part from one gun would not necessarily fit another gun. Whitney began making guns with machinery, so that all the parts were the same in each gun. This method of manufacturing goods in a factory, with interchangeable parts, helped to advance American industry.
In 1913, the automaker Henry Ford introduced the "moving assembly" line. This was a variation on the earlier practice of continuous assembly. By improving efficiency, it made possible a major saving in labor costs. A new breed of industrial managers began the careful study of factory operations with the aim of finding the most efficient ways of organizing tasks. Their concepts of "scientific management" helped to lower the costs of production still further. Lower costs made possible both higher wages for workers and lower prices for consumers. More and more Americans were gaining the ability to purchase products made in the United States. During the first half of the 20th century, mass production of consumer goods such as cars, refrigerators and kitchen ranges helped to revolutionize the ways in which Americans lived.

单选题 In the first paragraph, the author intends to tell us that
【正确答案】 B
【答案解析】[精析] 此题是对文章细节的考查。文章开头就指出了:Early American industries depended largely on skilled artisans working in small shops,意思是早期的美国工业很大程度上依赖于有经验的技工,在小作坊里工作。这句话也是第一段的主旨,与选项B符合。故选B。
单选题 The first factory in the United States was
【正确答案】 C
【答案解析】[精析] 此题是对文章细节的考查。文章第二段原句是:The first factory in the United States is generally dated to 1793,when an Englishman named Samuel Slater came to America to build a cotton cloth factory.He built the machinery from memory.意思是美国的第一家工厂可以追溯到1793年,一个叫Samuel Slater的英国人来到美国,创建了一家棉布工厂。他是凭自己的记忆成立了这个工厂。正好与选项C吻合。故选C。
单选题 Another important development was concerning
【正确答案】 B
【答案解析】[精析] 此题是对文章细节的考查。第三段开头第一句就点出了重大的突破就在于“mass production(大规模生产)”。故选B。
单选题 Which of the following statements is NOT true?
【正确答案】 D
【答案解析】[精析] 此题是对文章细节的推理。所给选项的核心词汇是Henry Ford,出现在文章第六段。选项D提到了他影响了商业系统,整篇文章都没有出现business此信息,故D选项是文章中没有提到的。故选D。
单选题 According to the passage, we can draw the conclusions except that
【正确答案】 D
【答案解析】[精析] 此题是对文章结论的推理。题干是问整篇文章中,我们不能得出的结论是哪个。选项 D意思是工业经理开始认真研究降低手续的方法。文章中也没有提到“industrial managers”这一概念,因此D选项没有在文中提及。故选D。
单选题 The passage is mainly discussing about
【正确答案】 A
【答案解析】[精析] 文章通篇都在讲美国早期工业的发展,文章的主旨也应该是介绍美国早期工业的发展。故选A。
